There are two ways to change the default tab size in Sublime Text2:

1. Go to Preferences -> Setting - Default and change the value of tab_size to whatever you want. In my case it was 2.

2. Go to Preferences -> Setting - User and add lines below:

{
	"tab_size": 2,
	"translate_tabs_to_spaces": true

Work around: Tell the API client to use HTTPClient as Faraday's default adapter after the require google api
